This article introduces you how to modify the database authentication mechanism in MongoDB3.0, the content is very detailed, interested friends can refer to, hope to be helpful to you.

Modification requirements: MongoDB3.0 's current authentication mechanism is SCRAM-SHA-1, which needs to be changed to the old authentication mechanism MONGODB-CR.

The methods are as follows:

> use admin

Switched to db admin

> db.system.version.findOne ({"_ id": "authSchema"})

{"_ id": "authSchema", "currentVersion": 5}

A currentVersion of 5 means that the authentication mechanism of the current database is SCRAM-SHA-1, which needs to be changed to a value of 3 for MONGODB-CR,currentVersion.

> var schema = db.system.version.findOne ({"_ id": "authSchema"})

> schema.currentVersion = 3

three

> db.system.version.save (schema)

WriteResult ({"nMatched": 1, "nUpserted": 0, "nModified": 1})

> db.system.version.find ()

{"_ id": "authSchema", "currentVersion": 3}

Here it means that the modification has been successful.

Create a database user

> use test

> db.createUser ({user: 'test', pwd:' test123', roles: [{role: "readWrite", db: "test"}]})

Successfully added user: {

"user": "test"

"roles": [

{

"role": "userAdminAnyDatabase"

"db": "admin"

}

]

View the authentication method:

> use admin

> db.system.users.find ()

{"_ id": "admin.admin", "user": "admin", "db": "admin", "credentials": {"SCRAM-SHA-1": {"iterationCount": 10000, "salt": "kAyNTjjA56SjKNB+voW/ow==", "storedKey": "S0QMFvrojLTl4fYN4zz6HL3rlRc =", "serverKey": "m0eym4YQikIufcR8JxcIRfdDrg ="}, "roles": [{"role": "userAdminAnyDatabase" "db": "admin"}]}

{"_ id": "test.test", "user": "test", "db": "test", "credentials": {"MONGODB-CR": "cf75a14725e3655983a84ea5f5b25438"}, "roles": [{"role": "readWrite", "db": "test"}]}
